DETAILED DESCRIPTION

FIG. 1 illustrates a set of earpieces 10 including a left earpiece 12Aand a right earpiece 12B. The left earpiece 12A has a housing or casing14A and the right earpiece 12B has a housing or casing 14B. A microphone70A is shown on the left earpiece 12A and a microphone 70B is shown onthe right earpiece 12B.

FIG. 2 illustrates an earpiece 12 which may be a left earpiece or aright earpiece. One or more processors or other intelligent controls 30are shown disposed within the housing 14 of the earpiece. One or morewireless transceivers 34 are operatively connected to the processors 30.The wireless transceivers 34 may include a BLUETOOTH transceiver, anultra-wideband (UWB) transceiver, or type of radio transceiver, a nearfield magnetic induction (NFMI) transceiver, or other type oftransceiver. One or more external microphones 70 is operativelyconnected to the processors 30 as are one or more internal microphonesor bone microphones 71. A global navigation satellite system (GNSS)receiver is also disposed within the housing 14 of the earpiece 12. TheGNSS receiver may be a Global Positioning System (GPS) receiver aGlobalnaya Navigazionnaya Sputnikovaya Sistema (GLOSNASS) receiver orother type of GNSS receiver.

FIG. 3 is a block diagram illustrating an earpiece. The earpiece mayinclude one or more sensors 32. The sensors may include one or more airmicrophones 70, one or more bone microphones 71, and one or moreinertial sensors 74, 76. Each of the one or more sensors 32 isoperatively connected to an intelligent control system 30. Theintelligent control system 30 may also be operatively connected to agesture control interface 36 which may include one or more emitters 82and one or more detectors 84. The gesture control interface 36 allows auser to interact with the earpiece through gestures or motions which aredetected by the gesture control interface and interpreted by theintelligent control system 30. One or more speakers 72 is operativelyconnected to the intelligent control system 30. One or more lightemitting diodes 20 are operatively connected to the intelligent controlsystem 30 potentially used to provide visual feedback indicative ofearpiece functionality or status. A radio transceiver 34 is shown aswell as a second transceiver 35 which may be an NFMI transceiver orother type of transceiver.

FIG. 4 illustrates one example of a methodology. In step 200 adetermination is made regarding a geospatial location using a GNSSreceiver. A geolocation or position is determined in step 200 and instep 202 a current location of the earpiece may be updated with thegeospatial location. In step 204 a determination is made as to whetherthe GNSS receiver is still available. It is contemplated informationfrom the GNSS receiver may not always be available for several reasons.First, in order to extend battery life of the earpiece or to otherwisebetter manage battery life the earpiece may turn off the GNSS receiverof the earpiece. Thus, when turned off the GNSS is not consideredavailable. There are other instances where the GNSS receiver may also beturned off. For example, if the temperature associated with the earpieceexceeds a threshold the GNSS receiver may be turned off as a part ofthermal management procedures. Regardless of whether the GNSS receiveris off or on it may not always be available to provide positioninformation. For example, if the earpiece is indoors, underground, in anarea where there is interference, the signal is being jammed, the GNSSreceiver is unable to get a satellite lock and unable to provideposition data. In these instances, when the GNSS is not available (forwhatever reason(s)), position may still be determined or tracked. Thisis performed by using information from one or more inertial sensorsproviding inertial sensor data. The inertial sensor data may be used tosense or infer movement. The earpiece may calculate a current locationbased on changes in position determined from the inertial data. Thusposition may be determined even though a geolocation is not availabledirectly from the GNSS receiver.

Below is one example of pseudo-code which may be used to determine acurrent location using a GNSS receiver if available and calculate acurrent location from a last known location and inertial data.

If GNSS_receiver_available:   current_loc = Get_geoloc( )      current_loc_time = Get_time( )     else:   current_loc =calculate_loc (current_loc, current_loc_time)   current_loc_time =Get_time( )

It is contemplated; however, this methodology may be implemented in anynumber of ways to reduce the processing resources used. For example,position may only be updated when the amount of change in position asdetermined by the inertial sensor exceeds a particular threshold.Similarly, if the inertial sensors determine there is very little changein position then the earpiece may turn off or power down or change modesof power consumption for the GNSS receiver to conserve resources. Forexample, the pseudo-code below illustrates one way of powering down theGNSS if the earpiece is not moving or has entered a power saving mode.

If not_moving or power_save_mode:   PowerdownGNSS( )  GNSS_receiver_available = 0

It is contemplated; however, the methodology may be implemented in anynumber of ways in addition to what is shown and described herein.

Instead of or in addition to having a GNSS receiver in one or moreearpieces, the one or more earpieces may have a charging case associatedwith them. FIG. 5 illustrates one example of a charging case 502 with acase housing 503. A first earpiece area 504 and a second earpiece area506 are shown for receiving earpieces 12A, 12B, respectively. Theearpieces 12A, 12B are matingly connected or otherwise come in contactwith contacts 508, 506. Thus, for example the contacts 510 of earpiece12A come into contact with the contacts 508 of the charging case 502.When earpieces 12A, 12B are received in the earpiece areas 504, 506, theconnections are made to allow for charging of the earpieces 12A, 12B aswell as data communication directly from the charging case 502 theearpieces 12A, 12B. FIG. 6 illustrates another view of the charging case502 to show the contacts 508 of the charging case 502 at a differentangle. The contacts may take on multiple forms, shapes, sizes,connectors, or materials.

FIG. 7 illustrates a block diagram of one embodiment of a charging case502. The charging case 502 may include a GNSS receiver 220, anintelligent control 222 operatively connected to the GNSS receiver 220,one or more earpiece connectors 508 for coming in contact with theearpiece and operatively connected to the intelligent control 222, awireless transceiver 224 operatively to the intelligent control 222, abattery 226 disposed within the housing of the charger 502 and aninterface/connector 228 which may be a USB type interface to allow thecharger 502 to be charged. The wireless transceiver 224 may receiveposition information determined by the GNSS receiver 220 and wirelesslycommunicate the position information to one or more earpieces when theone or more earpieces are not connected. The GNN receiver 220 may alsocommunicate position information to one or more earpieces when theearpieces are connected to the charging case.

It is contemplated in many applications the earpieces are not locatedfar from the charging case such as when a person is using the earpiecesat home, at work, at the gym, or while travelling. In addition, thecharging case may be plugged-in and charged more regularly and thebattery 226 may have greater capacity than any batteries in theearpieces. Thus, it may be advantageous in certain implementations toplace the GNSS receiver 220 in the charging case 502. Thus, theearpieces still have access to GNSS position data and can use the dataas an approximate position of the earpieces or calculate position basedon a combination of last GNSS position and movement of the earpieces asdetermined by inertial sensors of the earpieces as previously discussed.

FIG. 8 illustrates one example of a method. In step 300 a geospatiallocation is determined using a GNSS receiver. In step 302 the geospatiallocation is conveyed from the case to the earpiece. This can be throughan electrical connection such as when the earpiece is present within thecase or can through wireless communication. Alternatively, thegeospatial location may be conveyed wirelessly. Next in step 304, thecurrent location of the earpiece may update with the geospatiallocation. Then in step 306 a determination is made as to whether theGNSS receiver is available. This means there is a connection with thecase (either wired or wireless) and the GNSS receiver is receivinglocation information. If it is not, then in step 312 the currentlocation of the earpieces may be modified using inertial sensor datafrom one or more sensors of the earpiece. If it is, then in step 308 ageospatial location may be determined using the GNSS receiver and thecurrent location of the earpiece may be updated with the geospatiallocation.

Thus, an earpiece with a GNSS receiver or which uses a GNSS receiver inits case has been shown and described. The present inventioncontemplates numerous variations, options, and alternatives includingthe location of the GNSS receiver, the type of GNSS receiver, thespecific algorithms used, the type of materials, and tools used toimplement the invention, the number and type of sensors present, thenumber and type of transceivers present, and any number of othervariations.
